IMPROVEMENT IN HAIR-TRIGGERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern v Be it known that I, F. SGHENCK, of San Antonio, in the county of Bexar, and State of Texas, have invented a new and useful Improvement in Fire-Aims; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in. the art to mak'e and use the same, reference being had to'the accompanying drawings,

' forming part of this specification.

This invention relates to the arrangement of a hairtrigger of such a construction that it may be applied to-any of that class of fire-arms which has but one notch in the hammer for the cocked position of thesame.

When a fly is, used in the hammer, it may be appliedalso to such arms that have a secondor rest" notch in the hammer. I

It is'so constructed that it may be adjusted to any of the said arms, without the assistance of a gunsmith, the only tool required forthe purpose being a screw-driyer.

Figure 1 represents a side view of the arrangement, applied to a Henrys or Winchester carbine.

Figure 2 is an edge view of the guard.

Figure 3 is a sectional side view of the same, showing it applied to a fire arm whose hammer has a double notch.

Similar letters of reference indicate corresponding parts.

A; is the main trigger.

. To the front part of the main trigger is riveted or otherwise fastened a flat spring, a, which extends be yond the lower point of the trigger, for the purpose of ofi'erin g a yielding point of contact for the action-of the hair-trigger mechanism. 7

' B is the hair-trigger, and O the hair-trigger catch.

The hair-trigger B is pivoted to the hair-trigger catch 0, by a pin, 1), which serves as a pivot for the hair-trigger.

To the hair-trigger B is secured'a spring, 0, which serves to keep the hair-trigger in the position shown in figs. 1 and 3, that is, ready for firing.

D is the handle-catch, pivoted by the pin d to the guard E, as shown.

F is the hair-trigger spring, which is fastened to the guard behind the handle-catch D.

The joint B O is secured in the guard by a pin or screw, 6, which passes through the trigger B, and serves as a pivot for the same.

The spring F is secured to the guard by a screw or otherwise, and acts against the back endof the handle-catch, when the same is at rest, as by black lines in fig. 1, and above a point, 1, 'of the same.

The main trigger A, with the spring a, is secured in its original place inthe look.

I A pin or screw, g, passes through the guard, and

serves to support the hair-trigger catch 0, asshown.

To set the hair-trigger, the lower end of the handlecatch D is swung down, as shown by red lines in fig. 1. The upper point h is thereby carried iorward, and passes under. the main trigger A, the elasticity of the spring a, riveted to the mai 7 trigger, allowing it to pass under the mam trigger, to catch under the point i of the hair-trigger catch 0. A screw, 3, serves to regulate this catching of the point h with. the point i.

A gentle touch of the hair-trigger '13 causes the back end of the hair-trigger catchG to be elevated, thereby releasing the point h of the handle-catch from its hold underthe point i.

The action of the spring F causes the handle-catch D instantly to resume the position represented in black lines in fig. 1. v

The spring a of the main trigger having, in setting the hair-trigger, yielded to the point 7:, has now resumed its original position, and comes in violent contact with the point 1:, which disengages the main trigger A from its hold in the notch of the hammer, and, there being no second notch in which'the trigger might catch, fires the gun without the use of a fly in the hammer. Using a fly in the hammer, the same arrangement will fire any gun. v

This hair-trigger arrangement may be set before or afterthe cooking of the main-spring, and may be used or not, at pleasure, leaving it discretionary to pull the main trigger or to use the hair-trigger, when both the.

main-spring and the hair-trigger spring are cooked.

Fig. 3 illustrates a fire-arm having a double-notched hammer and fly, and provided with my improved hairtrigger attachment.

Having thus described my invention, 1 claim as new, and desire to secure by Letters Patent- The hair nigger attachment to the guard E, consisting of the-nair-triggerB, the hair-trigger catch 0,

the handle-catch D, and the spring F, all constructed and operating substantially as and for the purpose described.
